Déjà vu is just one of many uncanny kinds of déjà experiences

I was 16, and it was the spring of 1956. I remember the new leaves were beginning to sprout on the elm trees near where we lived in Oklahoma. I recall how happy we were that the road outside our home had finally been paved – it was now a lot quieter when cars drove past (and less dusty, too). And I remember that the high-school ‘sock hop’ dances had begun, where DJs played Elvis Presley’s first hit ‘Heartbreak Hotel’. But what I remember most from that spring was my first unsettling encounter with the impossible.



It started with a game. My friends and I decided to play hide-and-seek on our bicycles. One of us rode off to hide and, after some time, the rest fanned out throughout the neighbourhood trying to find him. This was in a small town on the northwest edge of Oklahoma City, which consisted mainly of small suburban homes with fenced yards, car garages and sheds, as well as trees and bushes that provided ideal camouflage. It didn’t take long until we decided that searching was hopeless: there were just too many places where he could be hiding. We gave up. But while riding back, an image appeared in my mind’s eye: I saw our quarry laying down his bicycle in the front yard of my house. We couldn’t have seen this directly because the yard was blocked by other houses. And yet, as we rounded the corner, I saw exactly what I’d pictured: our friend laying down his bicycle in the grass. I had seen it before seeing it – and in exquisite detail!


This experience, and others like it, contradicted everything I thought I knew about how reality functions and launched me on a quest that continues to the present day. At first, in the late 1950s and early ’60s, no one around me had any idea what I was talking about when I tried to explain these experiences. It wasn’t until 1970, while at the library of the National Institutes of Health near Washington, DC, that I finally found a knowledgeable librarian who knew that such experiences are called déjà vu, a French phrase meaning ‘already seen’. I learned that many others had had similar impossible experiences, too. I was not alone. This whetted my appetite. But my discovery of déjà vu led only to more questions. The deeper I delved, the more complex it became. ‘Déjà vu’ was not one thing. In fact, it was a better understood as a variety of experiences: ‘déjà experiences’.

Light Therapy holds promise as a treatment for Alzheimer's Disease

A new article, conducted by Lili Zang and colleagues from Weifang Medical University School of Nursing in Shandong Province, China, discusses a meta-analysis of 15 high-quality trials that investigated the impact of light therapy on individuals with Alzheimer’s disease (AD). The meta-analysis included 598 patients with mild to moderate Alzheimer’s disease, and it covered 15 randomized controlled trials conducted in seven different countries. Those trials were published between 2005 and 2022. Sleep Improvement Light therapy led to significant improvements in several sleep measures. It notably enhanced sleep efficiency, increased interdaily stability, and reduced intradaily variability, all of which are indicators of better sleep quality. Light therapy was associated with a reduction in agitation, depression, and caregiver burden among individuals with Alzheimer’s disease. A significant advantage over usual care was shown in reducing the severity of psychobehavioral symptoms, as assessed

Carvacrol: Health benefits from aromatic herbs (oregano, thyme)

Carvacrol is a phenolic monoterpenoid found in various essential oils. Oregano, thyme, and bergamot contain carvacrol. It boasts a range of beneficial properties for potential clinical applications. This compound has shown antimicrobial, antioxidant, and anticancer activities. It showed antimicrobial efficacy against food-borne pathogens like Escherichia coli and Salmonella. It is attributed to a unique combination of its chemical characteristics. Carvacrol, often used alongside thymol (another phenolic monoterpenoid found in these oils), exhibits high antioxidant activity and has been employed as a dietary additive to enhance the antioxidant status in animals (I.E. in poultry nutrition) Preclinical studies suggest promising anticancer properties of carvacrol, particularly in breast, liver, and lung carcinomas, through (proapoptotic) mechanisms involving elimination of DNA abnormalities. However, despite a well-defined toxicological profile, the lack of human trials hinders conclusive

Creatine for six months can improve long COVID fatigue

  A small study suggests that taking creatine as a supplement for six months may significantly improve clinical features of post–COVID-19 fatigue syndrome (long COVID). Those symptoms are: Fatigue Shortness of breath Chest pain Joint pain Cognitive difficulties often referred to as “brain fog.”  The study, conducted by researchers from the University of Novi Sad, Serbia, found that creatine supplements led to reduced fatigue and improved scores for various long COVID-related symptoms, such as loss of taste, breathing difficulties, body aches, headaches, and concentration problems.  Creatine is a natural compound found in small amounts in certain foods and produced by the body, mainly in muscles. It plays a crucial role in the Adenosine Triphosphate -Phosphocreatine (ATP-PC) energy system, which is the primary source of energy for short bursts of intense activities lasting from 1 to 30 seconds, like weightlifting or sprinting. Supplementing with creatine has been proven to increase the
